Pathway-Dependent Control of Chiral Phases for Higher Performance and Inverted Circularly Polarized Luminescence.

Chiral luminescent materials have garnered increasing attention for their exceptional ability to emit circularly polarized luminescence (CPL) along with their excellent applications. Here, a cyclohexylidene scaffold was conceptualized as a chiral source for developing higher performance CPL materials in term of simultaneously enhanced quantum yields (PLQYs) and dissymmetry factor. It was found that the axially chiral scaffold attached with a cyanostilbene showed a pathway dependent assembly route to form chiral luminescent liquid crystals and crystal upon fast and slow cooling, respectively.
